Abstract
A network access control device generates, in a tunnel-based access control network environment, a tunnel that connects a terminal application to the gateway of a destination network, on the basis of a tunnel between the terminal application and a gateway and a tunnel between gateways, thereby enabling safe transmission of a data packet from the terminal application to a destination node. It can include: a memory for storing a tunnel policy, a tunnel routing policy, and a tunnel table; and a control unit which generates tunnel information and data flow information on the basis of the tunnel policy, the tunnel routing policy, and the tunnel table according to a network access request of the terminal, and which transmits the generated tunnel information and data flow information to the terminal and the gateway of each network so that a tunnel between the terminal and the destination network is generated.
